Abnormal Psychology, 3e
1
Personality
• What is personality?
– Personality is a unique and long-term pattern of inner
experience and outward behavior
– Personality tends to be consistent and is often
described in terms of “traits”
• These traits may be inherited, learned, or both
– Personality is also flexible, allowing us to adapt to
new environments
• For those with personality disorders, however, that flexibility
is usually missing
Comer, Fundamentals of
Abnormal Psychology, 3e

Personality Disorders
• What is a personality disorder?
– An inflexible pattern of inner experience and
outward behavior
– This pattern is seen in most interactions,
differs from the experiences and behaviors
usually expected, and continues for years
Comer, Fundamentals of
Abnormal Psychology, 3e
3
Classifying Personality
Disorders
• A personality disorder is diagnosed only when it
causes impairments in social or occupational
functioning, or when it causes personal distress
– Personality disorders typically become recognizable
in adolescence or early adulthood
– Generally, the affected person does not regard his or
her behavior as undesirable or problematic
– It has been estimated that 9% to 13% of all adults
may have a personality disorder
Comer, Fundamentals of
Abnormal Psychology, 3e
4
Classifying Personality
Disorders
• Personality disorders are diagnosed on Axis II
of the DSM-IV-TR
• Those diagnosed with personality disorders are
often also diagnosed with an Axis I disorder
– This relationship is called “comorbidity”
• Axis II disorders may predispose people to develop an Axis
I disorder, or Axis I disorders may set the stage for Axis II
disorders, or some biological condition may set the stage
for both!
– Whatever the reason, research indicates that the
presence of a personality disorder complicates and
reduces a person’s chances for a successful
Comer, Fundamentals of
recovery
Abnormal Psychology, 3e
5
Classifying Personality
Disorders
• The DSM-IV-TR identifies ten personality
disorders and separates these into three
categories or “clusters”:
– Odd or eccentric behavior
• Paranoid, schizoid, and schizotypal personality disorders
– Dramatic, emotional, or erratic behavior
• Antisocial, borderline, narcissistic, and histrionic personality
disorders
– Anxious or fearful behavior
• Avoidant, dependent, and obsessive-compulsive personality
disorders
Comer, Fundamentals of
Abnormal Psychology, 3e
6
Classifying Personality
Disorders
• The various personality disorders overlap
each other so much that it can be difficult
to distinguish one from another
• The frequent lack of agreement between
clinicians and diagnosticians has raised
concerns about the validity and reliability
of these categories
Comer, Fundamentals of
Abnormal Psychology, 3e
7
“Odd” Personality Disorders
• The cluster of “odd” personality disorders
includes:
– Paranoid personality disorder
– Schizoid personality disorder
– Schizotypal personality disorder
Comer, Fundamentals of
Abnormal Psychology, 3e
8
“Odd” Personality Disorders
• People with these disorders display behaviors
similar to, but not as extensive as, schizophrenia
– Behaviors include extreme suspiciousness, social
withdrawal, and peculiar ways of thinking and
perceiving things
– Such behaviors leave the person isolated
– Some clinicians believe that these disorders are
actually related to schizophrenia, and thus call them
“schizophrenia-spectrum disorders”
Comer, Fundamentals of
Abnormal Psychology, 3e
9
Paranoid Personality Disorder
• characterized by deep suspicion or
mistrust of others
– Although inaccurate, the suspicion is usually
not “delusional”
• As a result of their mistrust, people with
paranoid personality disorder often avoid
relationships
Comer, Fundamentals of
Abnormal Psychology, 3e
10
Paranoid Personality Disorder
• symptoms can include hypersensitivity,
vigilance, and caution when dealing with
others
• Between 0.5% and 3% of adults are
believed to experience this disorder,
apparently more men than women
Comer, Fundamentals of
Abnormal Psychology, 3e
11
How Do Theorists Explain
Paranoid Personality Disorder?
• The proposed explanations of this disorder, like
those of most other personality disorders, have
received little systematic research
– Psychodynamic theorists trace the pattern back to
early interactions with demanding parents
– Cognitive theorists suggest that maladaptive
assumptions such as “People are evil and will attack
you if given the chance” are to blame
– Biological theorists propose genetic causes and have
looked at twin studies to support this model
Comer, Fundamentals of
Abnormal Psychology, 3e
12
Treatments for Paranoid
Personality Disorder
• People with paranoid personality disorder
do not typically see themselves as
needing help
– Few come to treatment willingly
– Those who are in treatment often distrust and
rebel against their therapists
• As a result, therapy for this disorder, as for
most of the other personality disorders,
has limited effect and moves slowly
Comer, Fundamentals of
Abnormal Psychology, 3e
13
Schizoid Personality Disorder
• characterized by persistent avoidance of social
relationships and limited emotional expression
– Withdrawn and reclusive, people with this disorder
are not interested in relationships with others
– People with schizoid personality disorder focus mainly
on themselves and are often seen as flat and cold
– The disorder is estimated to affect fewer than 1% of
the population
• It is slightly more likely to occur in men than in women
Comer, Fundamentals of
Abnormal Psychology, 3e
14
How Do Theorists Explain
Schizoid Personality Disorder?
• Many psychodynamic theorists,
particularly object relations theorists, link
schizoid personality disorder to an
unsatisfied need for human contact
– The parents of those with the disorder are
believed to have been unaccepting or abusive
of their children
Comer, Fundamentals of
Abnormal Psychology, 3e
15
How Do Theorists Explain
Schizoid Personality Disorder?
• Cognitive theorists propose that people
with schizoid personality disorder suffer
from deficiencies in their thinking
– Their thoughts tend to be vague and empty,
and they have trouble scanning the
environment for cues
Comer, Fundamentals of
Abnormal Psychology, 3e
16
Treatments for Schizoid
Personality Disorder
• Their extreme social withdrawal prevents
most people with this disorder from
entering therapy unless some other
disorder makes treatment necessary
– Even then, patients are likely to remain
emotionally distant from the therapist
Comer, Fundamentals of
Abnormal Psychology, 3e
17
Treatments for Schizoid
Personality Disorder
• Cognitive therapists have sometimes been able
to help people with this disorder experience
more positive emotions and more satisfying
social interactions
• Behavioral therapists have had some success in
teaching social skills
• Group therapy is apparently useful when it offers
a safe environment for social contact
• Drug therapy is of little benefit
Comer, Fundamentals of
Abnormal Psychology, 3e
18
Schizotypal Personality
Disorder
• characterized by a range of interpersonal
problems, odd (even bizarre) ways of
thinking and perceiving, and behavioral
eccentricities
– These symptoms may include ideas of
reference and/or bodily illusions
– People with the disorder often have great
difficulty keeping their attention focused;
conversation is typically digressive and vague
Comer, Fundamentals of
Abnormal Psychology, 3e
19
Schizotypal Personality
Disorder
• Socially withdrawn, people with
schizotypal personality disorder seek
isolation and have few friends
• It has been estimated that 2% to 4% of all
people (slightly more males than females)
may have the disorder
Comer, Fundamentals of
Abnormal Psychology, 3e
20
How Do Theorists Explain
Schizotypal Personality
Disorder?
– Schizotypal symptoms are often linked to poor family
communication and to psychological disorders in
parents
– Researchers have also begun to link schizotypal
personality disorder to some of the same biological
factors found in schizophrenia
• The disorder has also been linked to mood
disorders
Comer, Fundamentals of
Abnormal Psychology, 3e
21
Treatments for Schizotypal
Personality Disorder
• Therapy is as difficult in cases of schizotypal
personality disorder as in cases of paranoid
and schizoid personality disorders
• Most therapists agree on the need to help
clients “reconnect” and recognize the limitations
of their thinking and powers
– Cognitive therapists further try to teach clients to
objectively evaluate their thoughts and perceptions
• Antipsychotic drugs appear to be helpful in
reducing certain thought problems
Comer, Fundamentals of
Abnormal Psychology, 3e
22
“Dramatic” Personality
Disorders
• The cluster of “dramatic” personality
disorders includes:
– Antisocial personality disorder
– Borderline personality disorder
– Histrionic personality disorder
– Narcissistic personality disorder
Comer, Fundamentals of
Abnormal Psychology, 3e
23
“Dramatic” Personality
Disorders
• The behaviors of people with these disorders
are so dramatic, emotional, or erratic that it is
almost impossible for them to have relationships
that are truly giving and satisfying
• These personality disorders are more commonly
diagnosed than the others
– Only antisocial and borderline personality disorders
have received much study
• The causes of the disorders are not well
understood
Comer, Fundamentals of
Abnormal Psychology, 3e
24
Antisocial Personality Disorder
• Sometimes described as “psychopaths” or
“sociopaths,” people with antisocial personality
disorder persistently disregard and violate
others’ rights
– Aside from substance-related disorders, this is the
disorder most linked to adult criminal behavior
• The DSM-IV-TR requires that a person be at
least 18 years of age to receive this diagnosis
– Most people with an antisocial personality disorder
displayed some patterns of misbehavior before they
were 15 years old
Comer, Fundamentals of
Abnormal Psychology, 3e
25
Antisocial Personality Disorder
• Surveys indicate that up to 3.5% of people in the
U.S. meet the criteria for this disorder
– Caucasians are somewhat more likely to be
diagnosed than are African Americans
– The disorder is four times more common in men than
women
• Because people with this disorder are often
arrested, researchers frequently look for people
with antisocial patterns in prison populations
– Studies indicate higher rates of alcoholism and other
substance-related disorders among this group
Comer, Fundamentals of
Abnormal Psychology, 3e
26
Antisocial Personality Disorder
• Children with a conduct disorder and an
accompanying attention-deficit
hyperactivity disorder apparently have a
heightened risk of developing antisocial
personality disorder
Comer, Fundamentals of
Abnormal Psychology, 3e
27
How Do Theorists Explain
Antisocial Personality Disorder?
• Psychodynamic theorists propose that this
disorder begins with an absence of
parental love, leading to a lack of basic
trust
• Many behaviorists have suggested that
antisocial symptoms may be learned
through modeling or reinforcement
Comer, Fundamentals of
Abnormal Psychology, 3e
28
How Do Theorists Explain
Antisocial Personality Disorder?
• The cognitive view says that people with
the disorder hold attitudes that trivialize
the importance of other people’s needs
• A number of studies suggest that
biological factors may play a role
– Findings suggest that people with antisocial
personality disorder have lower levels of
anxiety and arousal, leading them to be more
likely than others to take risks and seek thrills
Comer, Fundamentals of
Abnormal Psychology, 3e
29
Treatments for Antisocial
Personality Disorder
• About 25% of all people with antisocial
personality disorder receive treatment for it, yet
no treatment appears to be effective
– A major problem is the individual’s lack of conscience
or desire to change
• Most have been mandated to treatment
– Some cognitive therapists try to guide clients to think
about moral issues and the needs of other people
• Hospitals have attempted to create therapeutic communities
– Generally, most of today’s treatment approaches
have little or no impact on the disorder
Comer, Fundamentals of
Abnormal Psychology, 3e
30
Borderline Personality Disorder
• great instability, including major shifts in mood,
an unstable self-image, and impulsivity
– Interpersonal relationships are also unstable
• People with borderline personality disorder are
prone to bouts of anger, which sometimes result
in physical aggression and violence
– Just as often, however, they direct their impulsive
anger inward and harm themselves
Comer, Fundamentals of
Abnormal Psychology, 3e
31
Borderline Personality Disorder
• Research indicates that as many as 10% of
outpatients and 20% of inpatients may meet the
diagnostic criteria for the disorder
– Many of the patients who come to mental health
emergency rooms are individuals with the disorder
who have intentionally hurt themselves
– Their impulsive, self-destructive behavior can include:
•
•
•
•
Alcohol and substance abuse
Reckless behavior, including driving and unsafe sex
Cutting themselves
Suicidal actions and threats
Comer, Fundamentals of
Abnormal Psychology, 3e
32
Borderline Personality Disorder
• Between 1.5% and 2.5% of the general
population are thought to suffer from this
disorder
– Close to 75% of those diagnosed are women
• The course of the disorder varies
– In the most common pattern, the instability
and risk of suicide reach a peak during young
adulthood and then gradually lessen with
advancing age
Comer, Fundamentals of
Abnormal Psychology, 3e
33
How Do Theorists Explain
Borderline Personality
Disorder?
• Because a fear of abandonment tortures
so many people with the disorder,
psychodynamic theorists look to early
parental relationships to explain the
disorder
– Object-relations theorists propose a lack of
early acceptance by parents
• Research has found some support for this view
Comer, Fundamentals of
Abnormal Psychology, 3e
34
•
How Do Theorists Explain
Borderline Personality
Disorder?
Some features of the disorder have also been linked to
biological abnormalities
– Sufferers who are particularly impulsive apparently have lower
brain serotonin activity
– Close relatives of those with borderline personality disorder are
five times more likely than the general population to have the
disorder
• A number of theorists currently use a biosocial theory,
stating that the disorder results from a combination of
internal and external forces
• Some sociocultural theorists suggest that cases of
borderline personality disorder are particularly likely to
emerge in cultures that change rapidly
Comer, Fundamentals of
Abnormal Psychology, 3e
35
Treatments for Borderline
Personality Disorder
• It appears that psychotherapy can
eventually lead to some degree of
improvement for people with this disorder
– It is not easy, though, for a therapist to strike a
balance between empathizing with a patient’s
dependency and anger and challenging his or
her way of thinking
– Furthermore, termination of therapy is often
incredibly difficult
Comer, Fundamentals of
Abnormal Psychology, 3e
36
Treatments for Borderline
Personality Disorder
• Contemporary psychodynamic therapy has been
somewhat effective when it focuses on the
patient’s central relationship disturbance, poor
sense of self, and pervasive loneliness
• Over the past two decades, an integrative
treatment approach, called “dialectical behavior
therapy,” has received growing research support
and is now considered the treatment of choice in
many clinical circles
• Group therapy has also been of some help
Comer, Fundamentals of
Abnormal Psychology, 3e
37
Treatments for Borderline
Personality Disorder
• Antidepressant, antibipolar, antianxiety, and
antipsychotic drugs have helped some
individuals to calm their emotional and
aggressive storms
– Given the high risk of suicide attempts by these
patients, their use of drugs on an outpatient basis is
controversial
• Some patients have benefited from a
combination of drug therapy and psychotherapy
Comer, Fundamentals of
Abnormal Psychology, 3e
38
Histrionic Personality Disorder
• extremely emotional and continually seek
to be the center of attention
– They often engage in attention-getting
behaviors
• Approval and praise are the lifeblood of these
individuals
– People with histrionic personality disorder are
often described as vain, self-centered, and
demanding
• Some make suicide attempts, often to manipulate
others
Comer, Fundamentals of
Abnormal Psychology, 3e
39
Histrionic Personality Disorder
• This disorder was once believed to be
more common in women than in men
– However, research has revealed gender bias
in past diagnoses
• The latest statistics suggest that around
2% of adults have this personality
disorder, with males and females equally
affected
Comer, Fundamentals of
Abnormal Psychology, 3e
40
How Do Theorists Explain
Histrionic Personality Disorder?
• The psychodynamic perspective was originally
developed to explain cases of hysteria and
theorists have retained their interest in the
disorder today
– Most psychodynamic theorists believe that, as
children, people with this disorder experienced
unhealthy relationships in which cold parents left
them feeling unloved
– To defend against deep-seated fears of loss, the
individuals learned to behave dramatically, inventing
crises that would require people to act protectively
Comer, Fundamentals of
Abnormal Psychology, 3e
41
How Do Theorists Explain
Histrionic Personality Disorder?
• Cognitive theorists look at the lack of substance
and the extreme suggestibility found in people
with the disorder
– Some propose that people with histrionic personality
disorder hold a general assumption that they are
helpless to care for themselves
• Sociocultural theorists believe the disorder is
caused in part by society’s norms and
expectations
– The vain, dramatic, and selfish behavior may be an
exaggeration of femininity as defined by our culture
Comer, Fundamentals of
Abnormal Psychology, 3e
42
Treatments for Histrionic
Personality Disorder
• Unlike people with most other personality
disorders, those with histrionic personality
disorder often seek treatment on their own
• Working with them can be difficult because
of their demands, tantrums,
seductiveness, and attempts to please the
therapist
Comer, Fundamentals of
Abnormal Psychology, 3e
43
Narcissistic Personality Disorder
• generally grandiose, need much
admiration, and feel no empathy for others
• Convinced of their own great success,
power, or beauty, they expect constant
attention and admiration from those
around them
• People with this disorder exaggerate their
achievements and talents, and often
appear arrogant
Comer, Fundamentals of
Abnormal Psychology, 3e
44
Narcissistic Personality Disorder
• People with this disorder are seldom interested
in the feelings of others
– Many take advantage of others to achieve their own
ends
• Less than 1% of adults display narcissistic
personality disorder
– Up to 75% of these are men
• This type of behavior is common among normal
teenagers and does not usually lead to adult
narcissism
Comer, Fundamentals of
Abnormal Psychology, 3e
45
How Do Theorists Explain
Narcissistic Personality Disorder?
• Psychodynamic theorists more than others have
theorized about this disorder, focusing on cold,
rejecting parents
– Object-relations theorists interpret the grandiose selfpresentation as a way for people with this disorder to
convince themselves that they are self-sufficient and
without need of warm relationships
– In support of this theory, research has found
increased risk for developing the disorder among
abused children and those from divorced families
Comer, Fundamentals of
Abnormal Psychology, 3e
46
How Do Theorists Explain
Narcissistic Personality Disorder?
• Behavioral and cognitive theorists propose that
narcissistic personality disorder may develop
when people are treated too positively rather
than too negatively in early life
– Those with the disorder have been taught to
“overvalue their self-worth”
– In support of this explanation, first-born and only
children score higher on measures of narcissism
• Finally, many sociocultural theorists see a link
between narcissistic personality disorder and
“eras of narcissism” in society
Comer, Fundamentals of
Abnormal Psychology, 3e
47
Treatments for Narcissistic
Personality Disorder
• This disorder is one of the most difficult
personality patterns to treat
– Clients who consult therapists usually do so because
of a related disorder, most commonly depression
– Once in treatment, the individuals may try to
manipulate the therapist into supporting their sense of
superiority
• None of the major treatment approaches have
had much success
Comer, Fundamentals of
Abnormal Psychology, 3e
48
Anxious Personality Disorders
• The cluster of “anxious” personality
disorders includes:
– Avoidant personality disorder
– Dependent personality disorder
– Obsessive-compulsive personality disorder
Comer, Fundamentals of
Abnormal Psychology, 3e
49
“Anxious” Personality Disorders
• People with these disorders typically display
anxious and fearful behavior
• Although many of the symptoms are similar to
those of anxiety and depressive disorders,
researchers have found no links between this
cluster and those Axis I diagnoses
• As with most of the personality disorders,
research is limited
– But treatments for this cluster appear to be modestly
to moderately helpful, considerably better than for the
other personality disorders
Comer, Fundamentals of
Abnormal Psychology, 3e
50
Avoidant Personality Disorder
• very uncomfortable and inhibited in social
situations, overwhelmed by feelings of
inadequacy, and extremely sensitive to
negative evaluation
– similar to social phobia
Comer, Fundamentals of
Abnormal Psychology, 3e
51
How Do Theorists Explain
Avoidant Personality Disorder?
• Theorists often assume that avoidant personality
disorder has the same causes as anxiety
disorders, including:
–
–
–
–
Early trauma
Conditioned fears
Upsetting beliefs
Biochemical abnormalities
• Research has not directly tied the personality
disorder to the anxiety disorders
Comer, Fundamentals of
Abnormal Psychology, 3e
52
How Do Theorists Explain
Avoidant Personality Disorder?
• Psychodynamic theorists focus mainly on
the general sense of shame felt by people
with avoidant personality disorder
– Some trace the shame back to early toilet
training experiences
Comer, Fundamentals of
Abnormal Psychology, 3e
53
How Do Theorists Explain
Avoidant Personality Disorder?
• Cognitive theorists believe that harsh
criticism and rejection in early childhood
may lead people to assume that others will
always judge them negatively
• In several studies, individuals reported
memories that supported both the
psychodynamic and cognitive theories
Comer, Fundamentals of
Abnormal Psychology, 3e
54
Dependent Personality Disorder
• a pervasive, excessive need to be taken
care of
– As a result, they are clinging and obedient,
fearing separation from their loved ones
– They rely on others so much that they cannot
make the smallest decision for themselves
• The central feature of the disorder is a
difficulty with separation
Comer, Fundamentals of
Abnormal Psychology, 3e
55
How Do Theorists Explain
Dependent Personality
Disorder?
• Psychodynamic explanations for dependent
personality disorder are very similar to
those for depression
– Freudian theorists argue that unresolved
conflicts during the oral stage of development
can give rise to a lifelong need for nurturance
– Other theorists argue that parents were
overinvolved and overprotective, increasing
their children’s dependency
Comer, Fundamentals of
Abnormal Psychology, 3e
56
How Do Theorists Explain
Dependent Personality
Disorder?
• Behaviorists propose that parents of those
with dependent personality disorder
unintentionally rewarded their children’s
clinging and “loyal” behavior while
punishing acts of independence
– Alternatively, some parents’ own dependent
behaviors may have served as models for
their children
Comer, Fundamentals of
Abnormal Psychology, 3e
57
•
How Do Theorists Explain
Dependent Personality
Disorder?
Cognitive theorists identify two
maladaptive attitudes as helping to
produce and maintain this disorder:
– “I am inadequate and helpless to deal with the
world”
– “I must find a person to provide protection so I
can cope”
• Such thinking prevents sufferers of the
disorder from making efforts to be
autonomous
Comer, Fundamentals of
Abnormal Psychology, 3e
58
Obsessive-Compulsive
Personality Disorder
• so preoccupied with order, perfection, and
control that they lose all flexibility, openness,
and efficiency
– They set unreasonably high standards for themselves
and others and, fearing a mistake, may be afraid to
make decisions
• These individuals tend to be rigid and stubborn
– They may have trouble expressing affection and their
relationships are often stiff and superficial
Comer, Fundamentals of
Abnormal Psychology, 3e
59
How Do Theorists Explain ObsessiveCompulsive Personality Disorder?
• Freudian theorists suggest that people
with obsessive-compulsive personality
disorder are anal regressive
– Because of overly harsh toilet training, people
become angry and remain fixated at this
stage of psychosexual development
• To keep their anger under control, they resist both
their anger and their instincts to have bowel
movements
• As a result, they become extremely orderly and
restrained
Comer, Fundamentals of
Abnormal Psychology, 3e
60
Treatments for ObsessiveCompulsive Personality
Disorder
• Although drug therapy and behavioral
therapy have been effective for people
with OCD (the anxiety disorder), people
with the personality disorder often appear
to respond better to psychodynamic or
cognitive therapy
Comer, Fundamentals of
Abnormal Psychology, 3e
61
What Problems Are Posed by
the DSM-IV-TR Categories?
• Some of the diagnostic criteria cannot be
observed directly
– The diagnoses often rely heavily on the
impressions of the individual clinician
– Similarly, clinicians differ widely in their
judgments about when a normal personality
style crosses the line and deserves to be
called a disorder
Comer, Fundamentals of
Abnormal Psychology, 3e
62
What Problems Are Posed by
the DSM-IV-TR Categories?
• The similarity of disorders within a cluster
or between clusters creates classification
difficulties
– People with quite different personalities may
be given the same diagnosis
• Individuals must meet a certain number of
criteria to receive a given diagnosis, but no
single feature is necessary for any
diagnosis
Comer, Fundamentals of
Abnormal Psychology, 3e
63
